摘　　要：对东部白松引种试验林个体进行了多年物候观测,并进行了种子育苗及异砧嫁接研究。结果表明:东部白松能够适应吉林市松花湖畔的自然环境,并能完成生长发育,4月20日树液开始流动,5月8日叶芽开始膨胀,5月13日抽枝,5月17日针叶开始展开,雄球花从芽中出现是在5月26日,5月31日开始散粉,4~5 d后达到散粉盛期,10 d左右散粉达到末期。雌球花从芽中出现是在6月4日,种子形成始于6月10日,球果成熟是在来年的8月20日左右。1年生实生苗平均苗高6.298 cm,平均地径0.954 mm,出苗率92%,根系体积20 cm^3,根系总吸收面积112.79 m^2,活跃吸收面积58.78 m^2;异砧嫁接接穗(东部白松)当年平均生长量8.56 cm,平均芽数5个,成活率90%。Phenological observation on the individual of Pinus strobus introduced experimental forest was carried out for many years,and the seedling breeding and different anvil grafts had been studied.The results showed that Pinus strobus could adapt to the natural environment of Songhua River in Jilin city,and completed growth and development normally.The sap began to flow on April 20th,the leaf buds began to swell on May 8th,the branches began to shoot on May 13th,the needles began to unfold on May 17th,and the male cones appeared from the bud on May 26th,and the powder begins to loosen on May 31th and reached the peak of loose powder after 4 to 5 days,the loose powder reached the end about 10 days.The female cones emerged from the bud on June 4th,the seed formation started on June 10th,the cones ripened around August 20th of the following year.About annual seedlings,the average seedling height was 6.298 cm,the average ground diameter was 0.954 mm,the seedling emergence rate was 92%,the root volume was 20 cm^3,the total root absorption area was 112.79 m^2,and the active absorption area was 58.78 m^2.At that year,the average growth of the scion grafted on different anvil(Pinus strobus)was 8.56 cm,the average number of buds was 5,and the survival rate was 90%.
